APPARTUS FOR PRODUGING RQLLS OF' NONFRAYIN G MATERIAL.

Application led February 1G),` 1924. Serial No. 693,337.

The present invention is a method and apparatus for the production ofbolts or rolls of material having the longitudinal edges ofthematerialtreated with a liquid of ad- 5 hesive material to preventfraying or ravelling of the edges.

It is an old-and well known practice in the art to cut rolls or bolts ofpiece goods, of relatively large width, by appropriate a1?- paratus intoa plurality of woundbolts or rolls of material. These goods or stripsare used for various purposes, such as piping and 'trinnning ofgarments, typewriter ribbons, and the like, and an adhesive or otherliquid is applied to the edges of the material or strips while in itswound or rolled condition to prevent fraying or ravelling of the edges.It is also old in the art to cut these goods or tape from straight laidmaterial or from material on the bias, accordingly as the use andrequirements to which the goods or tape are put necessitate. In bothcases, however, the unselvaged edges of the material 'or tape will frayif not made lfast in some appropriate manner. It has long been thepractice to apply a suitable liquid or adhesive to the edges of thematerial while in wound or'roll form with a hand brush, but this processis slow as only one side of the roll can be treated at a time, and theliquid is not uniformly spread.

It is the object of the present invention to overcome these drawbacksand to apply an even coating or film of unravelling liquid to both sidesof the roll simultaneously.

The invention resides in the method employed in producing rolls ofnon-ravelling material or strips, and in the novel structure of one formof apparatus specifically adapted for carrying out the method.

The process for carrying out the invention Yconsists briefly in cuttingpiece goods, either i straight laid or on the bias, transversely, toproduce a plurality of rolls or bolts of mate- 'rial 22 (Figs. 7 and 8)then treating the sides of the bolts or rolls of material with anedgebinding material, such as a liquid orsuitable coating, by passingthe bolts or rolls edgewise between rollers or other suitableapplilcator ,(Fig. 4), which will'apply the edging material to the sidesof the roll on the exposed edges of the material,- wherebysimultaneously the opposite side edgesof the material are treated withthe edge-binding material.' The rolls are thn permit-ted to dry andsubseucntly ready for packing or use, thus prouclng non-ravelling edgesm on the tape or strlp as shown in Fig. 8. This method conten'lplateswrapping or. applying about the circumferential surface' of eachindividual roll', a protecting covering, y (Fig. 7) suchas paper or thelike, to protect the face of the material from soiling or from excessamounts of non-ravelling binding material during the treating steps ofthe process, or in a plying the covering about the bolt or roll be orethe smaller rolls lare c ut therefrom.

Obviously this invention permits the utilization of a great variety ofinstrumentalities for producing the desired results and it willtherefore be understood that, by disclosing herein certain particularforms of structure, we confine ourselves thereto and to the operation tobe performed, only in so far as they 'carry into effect the principlesof the invent-ion. l

The accompanying drawings illustrate. the preferred form oftheconstruction, as at present devised, for carrying out the steps of thenovel method of producing rolls or bolts of material or tape havingalrough edge treated to prevent ravelling, but it is to be understoodthat the apparatus is susceptible to many changes/in construction andarrangements of p-arts without departing from the spirit of theinvention.

In the drawings: Figure l is a side elevation of the machine. Fig. 2 isa plan view of the machine. Fig. 3 is an elevation of the machinelooking at the'opposite side thereof.

Fig. 4 is a longitudinal sectional view taken through the machine,-substantially on line 4 4 of F ig. 2. f

Fig. 5 is a transverse sectional view taken substantially on line 5 5 ofFig. 2.

Fig. 6 is a similar view to Fig. 5 taken substantially on line 6-6 ofFig. 2. n c

Fig. 7 is a cross section through a roll'or rolls of material or tapeafter it has passed through the edging material and surrounded by anouter protecting covering, and

Fig. 8 is a prespective view-'of a roll of material or tape. aftervhaving `been subjected parts of the machine are mounted, said framebeing supported, in the present instance, by the legs 2.

Arranged pair of rollers 3 and 4 journaled respectlvely 1n bearings 5and 6. The bearings 5 are stational-il)T mounted on the framel while thebearings (i are slidably mounted, whereby the rollers may be. adjustedrelatively to each other to vary the openingsl or passage het wecn them.'.lhe two bearings 6. on opposite sides of the frame, aire connected bya rod 7 and a bar 8 which will permit the hearings to be shifted inunison, the under face of the bearings beinggrooved to .receive a rib 9on the frame. However, any other suitable construction maybe provided.The adjustment of the bearings 6 is effected by a rod 1() threadinglymounted in one end of the frame, as at 11, and having` a swivelconnection with the bar 8.

Arranged under each of the rollers 3 and 4 and between their respectivebearings are pans 12 and 13 respectively, which are shown assubstantially identical in construction, and

i are designed to contain a. suitable quantity of the edge bindingmaterial, such as a suitable liquid or adhesive. The pan 12 is suspendedat one end by hooks 14 engaging one of the cross rods 15, connecting thestationary brackets 5, the other end portion of the pan resting upon asupport 16, which is adjustable through the slot and thumb screwconnection 17 on the frame 1 to permit the pan to be adjusted withrelation to the roller 3 in order that the roller may enter the liquidtherein, and so that its circumferential surface will be covered orcoated therewith.

The pan 13 is substantially identical with the pan 12 except for itsmanner of support and specific manner of. adjustability with re spect tothe roller 4. In this case the pan 13 is adjusted by the thumb nuts 18on the bolts 19 which extend from the bearings 6 through slots 20 in theframe 1, and through a supporting bar 21 upon which the pan rests, seeFig. 6. By this construction the pan 13 is adjustable with the bearingsand moves therewith.

It will thus be seen that the rollers 3 and 4 are readily adjustable tobe separated sufficiently to correspond with the width of the roll ofmaterial or tape to be passed through themachine, and to properly feedthe rolls edgewise therethrough as indicatedl in Figs. 1 and 4. Byreason of the rollers 3 and 4 dipping into the adhesive in the pans 12and 13, their circumferential surfaces will be coated f with a film ofthe edging material and the transversely upon thc frame is a Spri n gs26 are i ntcrposed between the bearings 5 and and the block 24 to act inopposition to the adjusting bolts 25, whereby the wiping rollers 23 aremoved away from the rollers and 4 after the bolts 25 are correspondinglyadjusted, there being suitable hand wheels or grips 27 on the adjustingbolts 25.

The wiping rollers 23 are each rotated :from their resjwctive roller 3or 4 by gearing 23L and 23" respectively, the depth of the teeth betweenmeshing gears being suflicient to permit the required adjustmenttherebetween. In lieu of this drive connection any other may besupstituted which will perform the same resu ts. v

It will thus be seen that as the rolls 22 are dropped between therollers 3 and 4, they will feed the same therethrough and at the sametime apply to the opposite sides of the roll, and therefore to theopposite side edges of the material or tape composingthe roll, a film orcoating of suitable edging material which will be partially absorbed bythe edges of the material or tape, and which when dry will hold thethreads at the raw edges thereof intact.` against fraying or ravellingas shown at m in Figs. 7 and 8. It will be also observed that the amountof adhesive to be applied to the sides of the rolls can be regulated byre.

duing or increasing the film on the'rollers 3 an 4:

The rolls 22 may be fed through the rollers 3 and 4 as many times as isfound sufficient to effectively treat the side edges thereof, and itwill be obvious that by this method and apparatus the work can be doneefficiently with a greater saving of time and labor than by the presentmethod of applying the adhesive by hand to each roll.

A number of rolls canl be fed through the machine at the same time,according to the length of the rollers 3 and 4. To this end a suitablefeeding means is provided y which may take any suitable form, however,inthe present instance consists of an endless conveyor 30 having therolls arranged thereon in rows of three or four to the row. These rollsare fed from the conveyor to a guiding throat- 29 through which theygravitate to a point b-etween the rollers. After passing through therollers they are discharged upon a suitable chute conveyor 42, downwhich they roll to a drier. V

The means for operating the applying rollers 3 and 4 consists of a shaft31 suitably journaled on the frame 1, as at. 32, and being driven fromany suitable source of power:

The thro'at ,29 consists of two operable i parts aand b, the formerbeing stationarily mounted and the latter being supported from thebearing blocky 6 and movable therewith, so as to increase or decreasethe interior area of the throat to accommodate the size of rolls to befed through the machine.- The side edges of the throat are formed withflanges c,

which substantially close the sides thereof,-

and insure the delivery of the rolls between the rollers The roll 3 hason one end of its axis a beveled gear 33 meshing with beveled gear 34fast on the shaft 31. The roller 4 has a beveled gear 35 on one end ofits axis meshing with a beveled gear 36 slidably keyed' on the shaft bymeans of the key` 37. The gears 35 and 36 are maintained in mesh by abracket arm 38 secured to t-he slidable bearings 6, the outer end of thebracket 38 having a fixed bearing in which the gear 36 is journaled sothat it will at all times mesh with the gear 35 irrespectively of itsposition on the shaft;

As an auxiliary lock to maintain the bearings 6 in their adjustedpositions, bolts 39 eX- tend through the bearings 6 and through theslots 20 in the frame 1, andy have an anchor late 41 at their lowerends, the upper ends of the bolts 39 being threaded and receivinglock-nuts 40 which will bear against the `top surface of the bearings 6and bind the parts in their properly adjusted positions.

After the rolls 22 have passed through the coating members or rollers 3and 4 they are discharged edgewise onto an inclined chute for platform42, downwhich they will roll to a suitable drier, or collecting devices,not shown, in order that rolls 22 may not fall over sidewise after beingdischarged on the chute 42, guides 43 and 44 areprovided, the

guide 44 being adjustable to increase or decrease the width between theguide to accommodate the width of the rolls 22 being treated. The guide44 is shown as being adn justable through/the set-screw 46 movable 1nthe slot 45. .l s
